I would install a graphics card in my PC just for the occasional game, except it would ruin the whole concept of a completely #silentPC with zero moving parts. #0dBA #fanless

Even if I could managed to get a #PassivelyCooled graphics card, it would block the airflow, because it sticks out 90 deg from the motherboard. My open air case does have a card cage to twist it 90 degrees that I can install, but still.

Might need a new PSU, too. Mine is only 500 W (Seasonic Prime TX-500 Fanless)

Apparently the only halfway decent passively cooled graphics card was the Palit KalmX RTX 3050 6 GB, and is no longer made.

Graphics cards in general have a poor orientation for convection cooling. You can see that even if I installed this thing vertically, the fins would get no convection airflow, at all. And if I installed it normally, it would block all convection flow through my CPU cooler.

QuietPC in the UK says they have the KalmX 3050 in stock, but two years ago, when I tried to order my CPU from them, they couldn't fulfill the order because the international payment wouldn't go through, something that has never, ever been a problem before ordering from the EU or Asia, which I do every so often. Probably a #Brexit thing.

I ended up getting a much better CPU, though, a Core i5-12600K instead of the 12400T, and the 12600K runs just fine with my Noctua NH-P1 passive cooler.

Anyway, the PC I built in 2022 is:
Thermaltake Core P3 chassis
Gigabyte Z690 UD AX mobo
Intel Core i5-12600K CPU
32 GB Kingston HyperX Fury DDR5-4800 RAM
500 GB Samsung 980PRO SSD
Noctua NH-P1 cooler
Seasonic Prime TX-500 PSU

Cinebench R23 = 17513 (no overclock, -135 mV undervolt, 88Β°C under sustained load)

I've since added an old 500 GB SATA SSD just to install games (Halo Master Chief Collection and FFXIV), but I mean to put in a new 1 TB SSD with heatsink in the second m.2 slot.

This PC emits 0 dBA noise. Completely silent under full load. There would be no way to tell it was even on without the power lights and blinking activity lights. It sits in my bedroom at the foot of my bed behind my 50" 4K TV (which is now broken), and doesn't disturb my sleep. I have most of the LEDs taped over so they aren't so bright as to light up the room at night.

The only thing it doesn't do well is graphics-intensive games, but it held up just fine playing 6 simultaneous instances of BlueStacks 5 on 2 monitors running DanMachi Memoria Freese. (Yes, I was insane playing six accounts at once.)

The ambient noise level in my bedroom at night is about 30 dBA. It's eerie.
